Abstract: Provided is a chain guide and a chain transmission that can reduce sliding resistance between the chain and guide lips, and can maintain a consistent oil film between the guide lips and outer plates. Guide lips each include a first contact convex portion formed on an upstream end in a chain running direction, and a second contact convex portion formed downstream of the first contact convex portion. The first contact convex portion includes a first peak and a first upstream slope formed upstream of the first peak. The second contact convex portion includes a second peak and a second upstream slope formed upstream of the second peak. The dimension in the chain running direction from an upstream end of a guide rail surface to the first peak is set smaller than a chain pitch.

Abstract: A transmission guide comprises a synthetic resin shoe supported by and integrally molded with a synthetic resin base by two-part molding. A guide length retaining mechanism, which can be formed by one or more protrusions on the back of the shoe and one or more cooperating recesses on the supporting surface of the base, retains the shoe against longitudinal movement relative to the base. A guide width retaining mechanism, which can be formed by projections on the edges of the shoe and cooperating holes formed in side walls extending from the supporting surface of the base, retains the shoe against widthwise movement relative to the base.

Abstract: The present invention provides a toothed belt transmission that reduces noise and vibration resulting from the engagement between a toothed belt and a toothed pulley, and that improves the durability of the toothed belt. The toothed belt transmission in which a tooth height of a toothed belt and a tooth height of a toothed pulley are set so that when the toothed belt and the toothed pulley start engaging with each other, tooth tip parts of the toothed belt and tooth bottom parts of the toothed pulley contact each other before tooth bottom parts of the toothed belt and tooth tip parts of the toothed pulley contact each other.

Abstract: A chain guide is provided in which durability is increased, weight can be reduced, material cost is reduced, the uniformity of resin orientation is improved, dimensional errors, errors in shape, internal strains, and defects are reduced, and bending rigidity such as rigidity against deflection and torsion is augmented with a simple configuration. The chain guide is provided with reinforcing ribs at a guide main body. The reinforcing ribs include first inclined reinforcing ribs and second inclined reinforcing ribs that cross each other. A zone in which the reinforcing ribs are not present is provided in the intermediate portion between two support porting.
